Storm sash



Aug. 19, 1958 R. A. GILLESPIE STORM SASH 2 Sheets-Sheet 2 Filed April 26, 1954 United States Patent Ofiice STORM SASH Indianapolis, Ind.

Application April 26, 1954, Serial No. 425,434 9 Claims. (Cl. 20-55) This invention relates to storm sash, and more particularly to metal-frame storm sash. Its principal object is to improve the structure, reduce the cost, and facilitate the assembly of such sash.

In carrying out the invention in its preferred form, the rectangular border frame of the sash is constructed of extruded metal strip having in one side a groove for reception of the glass. At each corner of the frame the meeting rails are mitered and held together by a sheetmetal clip which extends around the corner and is provided at its edges with in-turned flanges received in transverse grooves extending across the outer faces of the rails. The grooves and flanges are disposed at a slight oblique angle so that when the clip is forced into the grooves by movement perpendicular to the plane of the sash the meeting rails will be drawn tightly together.

If, as is usually desirable, a sash is to incorporate a plurality of panes of glass, adjacent panes are separated by a muntin. The muntin may be an extruded metal strip of H-shaped cross-section having its ends abutting against the inner face of the border frame. To secure each end of the muntin to the adjacent rail of the frame, I prefer to employ a sheet-metal clip having along opposite edges flanges received in grooves in the muntin and side rail. Desirably, the grooves and clip-flanges depart slightly from parallelism so that as the clip is forced home by movement transverse to the muntin the end of the muntin will be drawn tightly against the side rail. Rail-grooves which receive the clip-flange may extend continuously throughout the periphery of the frame to receive a seal bearing against the window frame when the storm sash is in place.

Hangers for supporting the sash from the conventional hooks at the top of the window frame may take the form of sheet-metal stampings which extend through slots in the upper rail of the sash frame. The lower ends of such hangers are provided with ears which prevent upward withdrawal of the hangers through the slots, and the hangers are held in place by the glass received in the upper rail.

If desired, the storm sash may include a ventilator comprising fixed and movable plates having openings which can be positioned in or out of alignment with each other in sliding movement of the movable plate. If a ventilator is provided the lower pane of glass in the sash does not extend to the lower border frame but is received in a glazing rail similar to the muntin, and the ventilator plates are supported between such glazing rail and the lower sash rail. The lower glazing rail and the lower sash rail may also support sliding locking plates for holding the sash in position on an associated window frame.

The storm sash shown in the drawing comprises an upper rail ill, a bottom rail 11, and side rails 12 assembled to form a rectangular frame. Conveniently, all rails are of identical crosssection such as is illustrated in Figs. 3, 6, and 7 and may be lengths of extruded aluminum or other appropriate metal. As shown, the stock from which the side rails are cut is provided with spaced inner and outer flanges 15 and 16 defining between them a groove for reception of a pane of glass and a U-shaped sealing strip or packing 17 embracing the edge of the glass. From the base of the channel defined by the two flanges 15 and 16 there extends a groove 18. The groove 18 is substantially narrower than the glass-receiving channel and its outer wall is desirably flush with the inner face of the outer flange 15. The outer face of the stock is provided with a longitudinal groove which receives a sealing strip 29 of suitable resilient material adapted to bear against the outer face of the window frame in association with which the storm sash is to be used.

The rails constituting the frame are assembled around the glass after having been cut to length with mitered corners, as will be clear from Fig. 4. For the purpose of holding adjacent rails together at each corner of the frame, I prefer to employ a sheet-metal clip 22 bent into an L-shape in cross-section and providing along its edges with inturned flanges 23 grooves extending transversely across the outer faces of the rails near their ends.

so that each leg of the metal clip 22 will be slightly broader at one end than at the other. In assembling, the two rails are brought together and a clip 22 is positioned as indicated in dotted lines in Fig. 5 with the flanges 23 at the broader end of the clip inserted into the grooves in the rails. Because of the obliquity of the clipflanges and grooves, the operation of forcing the clip to the final, full-line position indicatedin Fig. 5 will draw the mitered end faces of the rails firmly together. As will be clear from Fig. 4-, the flanges 23 are desirably not perpendicular to the clip-legs with which they are respectively associated but instead are disposed at acute angles to such clip-legs, and the grooves in the rails are similarly inclined. This inclination of the flanges and the grooves which receive them prevents the clip from spreading and the flanges from leaving the grooves.

Hangers 25 for supporting the sash from the conventional hooks 25' on the window frame may take the form generally U-shaped stampings the parallel legs of which extend through slots 26 punched in the upper rail 10 in the plane of the groove 18 therein. As shown, the hangers are adapted for insertion into the top rail 10 from above and carry the weight of the storm sash through ears 27 and 28 projecting outwardly from the lower ends of their parallel legs. The slots 26 have lengths substantially greater than the width of the para1- Patented Aug. 19, 1958 adapted to be received in Such grooves and the flanges they receive have a slightly oblique disposition (Fig. 5), i I

lel legs of the hanger. 'One of the ears, shown as the ear 27, lies wholly within the groove 18 when the hanger is in place; but the other car 28 has an upward extension 29 which is adapted to lie in the associated slot 26, and which, when so disposed, prevents any movement of the hanger longitudinally of the upper rail 10. The hangers are applied to the upper rail before such rail is positioned on the glass, the ear 28 being first inserted through the one slot 26 and into the groove 18 with the hanger in an inclined position, as indicated in dotted lines in Fig. 4, following which the hanger is swung to bring the other ear through its slot 26. Upon subsequent movement of the hanger into the full-line position shown in Fig. 4 the ear-extension 29 enters its associated slot 26 to locate the hanger longitudinally of the upper rail. After such rail has been applied to the glass, the latter prevents the extension 29 from dropping out of its associated slot.

The particular storm sash shown in the drawing has upper and lower panes of glass 30 and 31 separated by a mutin 32. Such. muntin, as will be clear from Fig. 7, is conveniently of H-shape in cross-section and may be formed as extruded metal. Its ends abut the inner edges of the side rails 12 and are secured thereto by sheet-metal clips 33 having along their edges flanges 34 (Fig. 6). One of such flanges may be received in the rail-groove which also receives the sealing strip 20, while the other flange is received in a transverse groove in the muntin. Desirably, the latter flange and the groove which receives it have an oblique disposition, as will appear from Fig. 2. Further, the flanges 34 are disposed at an acute angle to the body of the clip 33, as shown in Fig, 6. When a clip 33, disposed below (Fig. 2) with its one flange in the rail-groove and its other flange entering the muntin-groove, is forced upwardly to its final position, the muntin will be drawn and held firmly against the side rail.

In thewindow shown in the drawings, the lower pane 31 does not extend to the lower rail 11 of the sash but instead is received at its lower edge in a lower glazing rail 36. spaced upwardly from the lower sash-rail 11 to provide for the reception of inner and outer ventilator plates 40 and 41. The lower glazing rail 36 may be of the same cross-section as is the muntin 32. The outer ventilating plate 41 extends completely across the lower portion of the sash-frame, its ends being received between the flanges and 16 of the'side rails 12. Such outer ventilator plate is conveniently formed of sheetmetal cut along its'upper edge to provide end tongues 43 and a center tongue 44 and along its lower edge to provide end tongues 45 and a center tongue 46. The metal across the ends of the plate and between the tongues is bent to extend perpendicularly to the plate and form a flange 47 which, except for the interruptions resulting from the-presence of the tongues, is continuous throughout .the periphery of the plate. The width of the flange 47 (see Figs. 7-10) is such as to enable it to. fill the channels in the side rails 12, bottom rail 11, and lower glazing rail 36. The tongues 45 and 46 lie in the groove 18 of the lower glazing strip, while the tongues 43 and 44aseat against the web of the lower glazing strip, as will be clear from Fig. 7.

The inner ventilating plate 40 is formed of a sheetmetal strip having its edges bent to provide flanges 50 so that it will nest within and be guided for sliding move- 1'."

ment relative to the outer plate 41. As is common, the innerand outer plates are provided with openings 51 which-are moved into and out of alignment with each other as the inner plate slides. To limit movement of the inner plate between positions in which the ventilating openings are fully open and fully closed, a portion 52 of the upper flange 50 thereon may be offset upwardly to providea tongue located in the gap in the flange 47 at the. upper, center tongue 44 of the outer ventilating plate.

Tozstiifen the construction at the bottom of the sash,

i the outer ventilating plate is desirably connected to-the lower rail 11. For this purpose, an upper corner of the tongue 46 may be cut away, as indicated at 53 in Fig. 10 to receive a boss 54 formed by inward displacement of a portion of the flange 15 of such lower rail.

The particular window shown in Fig. 7 has a frame 60 which includes at its outer face a flange 61 forming the outer wall of a guideway for the upper window sash 62. Such flange 61, which extends along the side mem- Q bers of the window frame to the bottom of the opening therein, provides a convenient means by which the storm sash can be secured in place through appropriate locking means embodied in the storm sash. The locking means shown in the drawing comprises a pair of locking plates 65 which are conveniently similar and are mounted for horizontal sliding movement between the bottom rail 11 of the storm sash and the lower glazing rail 36. The body of each locking plate 65 is received within the channels of the lower rail 11 and lower glazing strip 36, and the vertical edge portions of the locking plate are offset inwardly of the window, the material of the plate at each offset being notched to clear the flanges of the lower rail 11 and lower glazing strip 36. Each offset portion of the locking plate forms a locking finger 68 adapted to lie against the inner face of the frame-flange 61. Each locking plate is slidable between a locking position shown in full lines in Figs. 8 and 9 and a retracted position shown in dotted lines in those figures. In the latter position, the locking plates clear the edges of the framefianges 61 to permit installation or removal of the storm sash, but in locking position the fingers 68 lie against the inner face of the frame-flange 61 and hold the sash firm-- ly in engagement with the window frame. Sliding movement of each locking plate may be limited by providing it at its lower edge with a tongue 69 which extends into a gap in the flange 47 at the end tongue 45.
